Not my cup of tea (am a tad claustrophobic) but I do find it interesting and efficient.
I mean, what do we do in a hotel anyway? We sleep. We watch TV. We eat a bit. I’d prefer to have one big enough to have BF in there with me, but this is a good quick fix.
The Japanese use it for business, or if they have to work early tomorrow and cannot make it back home for that night.
Another use, is if you accidentally missed your train and have to bunk out for the night.
Via Pics Roll where you can find even more pictures of these capsule hotels.
